Why these settings

The Cort X300 humbuckers have higher output than Alex G's single-coil offset, so rolling guitar volume to 8 and setting ISF to 3 emulates a scooped, woody Fender clean platform. The ID:Core V3 lacks dedicated mid and presence knobs, using an ISF control instead—keep treble low at 4 to tame the humbucker attack and capture the tape-like, lo-fi top end. Setting gain to 4 on Clean Warm introduces a faint touch of compression without breaking into harsh digital clipping.

PRO TIPPick lightly with the fleshy side of your thumb or use a thin, flexible nylon pick near the neck joint rather than hard near the bridge to soften your initial transient and capture that bedroom-recorded intimacy.
